Add shared macros for stringizing and converting ANSI string constants

(in particular defined by macros) to wide string constants.

Convert existing locally-defined stringizing to use the shared macros.

Unit tests for the shared macros.

This also fixes a minor bug in ceee_module_util.cc where I
accidentally quoted a string constant I only meant to convert to wide
(this caused no bug, but was unintended, so the change in semantics
in that file in the current change is intentional).

BUG=none
TEST=automated tests
